How Do Remote Controls Work?

Generally, there are two types of remote controls: infrared (IR), and radio frequency (RF). Infrared remote controls work by sending pulses of infrared light to a device, while RF remote controls use radio waves in much the same way. Pragmatically, the biggest difference between the two is range. IR remote controls require a clear line of sight to the receiving device and their range maxes out at about 30 feet (9.14 meters). RF remote controls can go through walls and around corners, with a range of roughly 100 feet (30.48 meters)

Most home entertainment components such as stereos, televisions and home entertainment centers use IR remote controls. The remote contains an internal circuit board, processor, and one or two Light Emitting Diodes (LEDs)

When you push a button on a remote control, it transmits a corresponding code to the receiving device by way of LED infrared pulses. The idea is somewhat akin to flashing an SOS signal, but instead of letters, the flashing LED light is transmitting a series of 1s and 0s. The "1" might be represented by a long flash, while "0," a short flash. A receiver, built into the component, receives the pulses of light and a processor decodes the flashes into the digital bits required to activate the function

Along with the desired function, remote controls must also piggyback other data. Firstly, they transmit the code for the device they are controlling. This lets the IR receiver in the component know that the IR signals it is picking up are intended for it. It essentially tells the component to start listening. The function data follows, capped by a stop command to tell the IR device go back into passive mode

Some remote controls can be very finicky, requiring the user point the remote directly at the component. This is due to a weak transmitter. Changing the batteries can help, but if the transmitter itself is poor, pulses are transmitted in a narrow beam. More robust IR transmitters, and remote controls with double LEDs, transmit broader beams that allow the user to point the remote in the general direction of the transmitter

Sometimes it happens that a recliner or favorite spot on the couch does not have a clear line-of-sight to the entertainment center or television. Often a coffee table or some other object is in the way. When this happens we find ourselves raising an arm, trying to control the object "around" the device. This can get quite annoying, but there's an easy alternative

Since light bounces off objects it is sometimes more convenient to point remote controls towards a flanking wall or even the ceiling to change a channel or send a function command. The light will bounce off the surface of the wall or ceiling and scatter. If you bounce it at an advantageous angle, the scattering light will reach the component. Often it's easiest, with elbow resting on an armrest, to flip your wrist back and point the remote up at a wall behind you. This can work quite well, even though the remote is pointing in the exact opposite direction of the component. Once you find the easiest sweet spots around the room from which to bounce your signal, you can use these instead of struggling with trying to get around your obstructed line of sight

Garage door openers, alarm systems, key fobs and radio-controlled toys use RF remote controls. RF remote controls work essentially the same as IR remote controls, except they use radio waves. As stated, radio waves can also penetrate walls and go around objects and corners, making RF arguably more convenient than IR

Some high-end entertainment systems come with RF remote controls for expanded remote range. There are also IR-to-RF remote control converters that allow IR remote controls to extend their range through utilizing a RF translator that basically acts as a middleman. The RF converter relays the IR signal in RF waves to get it further. The converter on the component side reverts the RF signal back to IR so the component can understand it

How to Build a Wireless Remote Control:

Simple wireless devices use various components to activate an infra-red signal that broadcasts to a receiver box, allowing the user to program the control. Basic wireless remote controls simply turn a device on or off. Components used in a wireless device can be found at most electronics outlets and hobby shops. Specialized retail establishments have pre-packaged kits that can be used by a beginner. At the very least, even experienced electronics enthusiasts use pre-made remote control boxes due to the simplicity of their design, including ergonomic support. The structure of the wireless remote control provides a builder with not only knowledge but the reasons a receiver can be controlled by the device

Open the remote control housing and place a push button switch on the side. In the upper right corner of the housing, fasten a 3-volt battery holder. Be sure enough room is available to install and remove the battery

Run a wire from the push button switch and link to the 3-volt battery holder at the negative connection. Attach another wire to the push button switch and lead it to the Meg 1/4W resistor and the NPN silicon transistor. Run a third wire from the Meg 1/4W resistor and attach it to the 22K 1/4W resistor and and the PNP silicon transistor

Position the infra-red LED on the front of the housing. Attach the LED and run wires to both transistors. From the 22K 1/4W resistor, run a wire to the C220.01uF 16v ceramic disk capacitor. Run another wire between the NPN silicon transistor and the ceramic disk capacitor

From the positive connector on the 3-volt battery holder, connect a wire to the PNP silicon transistor. This will allow for proper current flow in a closed circuit. Ensure the push button switch is positioned to "off" and place a 3-volt battery into the holder. Close the remote control housing

Point the remote control at a receiver, making sure the LED on the control is aimed at the LED of the receiver. Push the button and the receiver should power on and off. To adjust the receiver to be programmed, point the remote control and hold down the push button switch. Adjust the pot or taper on the receiver

I use this to turn carport lights on and off from a distance of about 80'. It works even through a plywood wall and a metal door! One note: It may not work if you just quickly "punch" the button. You need to hold it down for about a half second so the relay can open or close the switch.

Not much to this product. Press button to turn product on, press off to turn it off. So far has worked as promised every time. I have it about 12 feet from the light I want turned on and

Works Nicely, Setup is Tricky

Works as expected. The only surprise was that you have to hold the button in for a second for it to work. I initially thought it wouldn't make it through a few walls even though the distance was only about 40 feet, but holding the button down for a second (vs. just a quick blip) did the job.

I had a hard time getting this device to pass the initial setup. Taken from a review on another site:
<br/>
<br/>It works like a charm, just DON"T read the manual. There was something definitely LOST in translation because the manual isn't clear as to how you get out of 'setting' mode and into 'measuring' (in this case triggering) mode.
<br/>
<br/>To exit setting mode - after you set your channel - you need to: "Turn the jog dial one click clockwise while pressing the 'Mode' button.""

This is good, it got a small blinking led to find the misplaced items. I am really satisfied with this Wireless Relay Module.

Very Cool, But Not Required

00:00:00 04-05-2011

This radio module works just fine. It's immediate; there's never a delay from the moment I press the trigger until the flashes fire. Of course, I don't have a big home studio, so I haven't tried it from very far away. It's not too expensive and I recommend just getting it if you're running PocketWizards. However, if you're tight on money, you can do without it. It's just cooler with one.

You can get the same exact item cheaper here. i looked around more, i found it too much to pay 50 bucks for this. original sekonic RT-32 module, just named different. great item by the way. must have
